A Silicon Valley jury has ordered Samsung Electronics to pay Apple $290 million for copying vital iPhone and iPad features.

The verdict Thursday covers 13 older Samsung devices that a previous jury found were among 26 Samsung products that infringed Apple patents.

The previous jury awarded Apple $1.05 billion. But U.S. District Judge Lucy Koh ordered the new trial and tossed out $450 million of the damages after concluding the previous jury miscalculated the amount Samsung owed.

Samsung appealed that verdict and is expected to appeal the latest verdict.

A third trial is scheduled for March to consider Apple's claims that Samsung's newest devices on the market also copied Apple's technology.
